TargetExternalSymbol is considered to be an immediate and not a register,
so machine verifier emits an error:

  *** Bad machine code: Expected a register operand. ***
  - function:    static_offset
  - basic block: %bb.0 bb (0x560e9b306028)
  - instruction: %3:int64regs = MoveParamI64 &static_offset_param_1
  - operand 1:   &static_offset_param_1

The patch adds variants of this instruction with an immediate operand
for byval arguments on 64-bit and 32-bit targets.
